saw saharienne.

Application inea April 1eI This invention relates to saw Sharpeners and more partlcularly to a hand operated deat a single operation.

An important object of the invention is the provision in a structure of this character of means for simultaneously supporting a plurality of saw liles in parallel relation of such character that the saw iiles may be canted `to `present an angle thereofto the teeth of the saw in any desired position. i A further object of the invention is to pro- 4vide a :trame having means for holding saw .tiles in this manner and having further means whereby the angle of the liles with relation to the longitudinal axis of the frame may be altered while maintaining the parallelism and rotated adjustment thereof.

. A still further objectief the invention is to provide a device of this, character in which the adjustments may be very readily accomplished, which may be readily and durably constructed and which will be a general improvement inthe art, j y i These and other objects I attain by the construction shown in the accompanying draw ings, wherein for the purpose oi' illustration is shown a preferredembodiment otmy invention and wherein Figure 1 is a plan viewof saw tiling apparatus constructed in accordance with .my in-1 vention, the tiles being illustrated as canted in dotted lines; j j

Figure 2 is a section on the line 2-2 oi' Figure 1; i j j j V` Figure 3 is a longitudinal sectional view; Figure t is `a combined perspective of the tilting mechanism; j t Figures 5 and 6 are enlarged fragmentary detail views showing the operation of the tilting mechanism and illustrating two extreme positions of the tile; j

Figure 7` is a section on the line 7-7 of Figure 1. i p j i i j Referring nowinore particularly to the drawings, the numeral 10 generally desig` nates a rectangular `frame,lone-ot the end members 11 and 12pt which is removably mounted and adjustablelongitudinally of the trame. In the present instance, the side i membersl ofthe `frame and the end member 11 are disclosed as having opposed `ears la and lifor coaction with clamping .screwsv 1926,` Serial No. 101,749.

1G. Theend member 11 has projecting webs 17 operating in slots 18 formed in the side members to guide the end member in its movements. Each end member has attached thereto a handle 19. The end members 11 and 12 have their inner faces channeled and in the channel o1 the end member 11 is slid ably mounted a plate 2O having openings 21 for the reception oi". the tip or smaller ends of files F. As` more clearly shown in Figure 3, these openings increase in diameter to ward the outer face of the plate. rfhe end member and the adjacent portion of the handle 19 are channeled in alignment with these openings, as indicated at 22, so that the tips oi' the tiles may extend thereinto. The pla-te 20 is adjustable transversely of the end. member in its channel and is held in adjusted positions by a springpressed and supported pin 23 extending through Athe upper wall of the channel and into a selected. one of a series of openings 2l1`formedin the edge of the plate; i i i j In the channel of the end member 12 is arranged an` assembly consisting of inner and outer plates 25 and 26 held in spacedrelation at their corners byl blocks 27 and at their lower edges by a strip 28, the upper edge oi which `is provided with obtusely angular notches 29. i Slidablebetween the plates is an oscillating bar 30, the lower edge of `which slides upon the upper 'face of the bar 28 and the ends of which extend between the blocks 27. `.The plate is `formed to provide shoulders 31 which will engage the upper blocks 27 and limit sliding movement of the oscillating bar. This oscillating bar has in its lower face notches 32 corresponding .in number and arrangement with the notches 29 and coacting therewith to receive the taner ends of liles F. By shitting the bar to the right or to the left, the angular position of the tile may be rotatably adjusted as will be obvious by an inspection of Figures 5 and Gf Means are provided to pern'iitthis adjustment comprising a spindle 43? journaled in the plates 25 and 2G and having secured thereto a pinion 3a in alignment with the oscillating bang() and coacting` with a rack formed in the upper sui-:face thereof. The inner end of this spindle projects inwardly of the inner plate and has secured thereto a milled operating head 3G. The plate 26 in alignment with the notches 29 of the bar 28 has formed therein openings 37 for the passage of the files in which the files may rotate freely. The walls of the notches flare toward the outer face of the bars 28 and 30 so that the lile is gripped and yet at the same time may be canted, as indicated in Figure 1. rIhe plate has a slot 38 permitting passage of the tangs of the files whilepreventing passage of the butt or larger ends thereof.

In the use of the device, files are inserted thereto by adjusting the end member 11 outwardly-or entirely removing the same and inserting the tang ends of the files through the openings 37 and notches 28. The tips of the files are then engaged in the openings 9.1 and the end member 1l adjusted to its proper position. The files will then be held in parallel relation and may be rotatably adjusted to obtain the proper angle of the cutting face of the file by rotating the milled head 3G which preferably has indicia coacting with a fixed indicator upon the frame to show the position'in which the files are disposed. If itis desired, as many operators desire, that y `the files be arranged at an angle to the frame,

this may be accomplished by adjusting the plate 2() untill the desired angle is attained.

Since it is obvious'that the structure hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such sdpecific structure .except ashereinafter claime Having described the invention, I claim 1. lAsaw sharpening device comprising a metal frame designed to hold any desired number of files between theends thereof,
